lle it known that We.. (Vif-Linens Pi. Riofr- 1 N. a citizen oi" the hinted States. and

lileriwr t'r'ro licotmen, a citizen fot l fiernmny. residing: at Francisco, in the f-ounty oie `ta'an llrainfiro. Starte of `Caliu'iw and useful 'l`url'ornia, have invented bine-Vine `{li \.aiun', et which i Ytollowing lu is a sijieoilioatiou in suoli iiull and clear terres as will enable their, ,skilled in the ii-t to oonstruet and use the saine.

This intention relates to a lluid pressure turbine and an obiei't oi theJ invention is to proilurfo i: turbine capable oi operatingr any7 desired vrotor apparatus to convert Vduid pressure into motion.

Another object of the invention is to prodiufe :i fluid. pressure'turbine 'v-:hieh will hare more rea ting blares in a ven space than many terms oi turbines and vwhich will be so shaped as to enable the steam liuid used to passioutwardly ,troni the rotor lo a shell like stator and then inwerdlv to Vthe rotor ig'ain esi'aping therefrom at tfie end whereby the number et moving' parts et the engine is musiderahly` reduced.

lll-theiohieots el the invention will appear as the desi'liption proceeds.

.lu embodiment ot the invention is shown in the accompanying drawings in Whir-h the .same reference numeral applied to the salue portion throughout.v but we are aware that there may be modifications thereof.

The shell is also den jed inwardly as at to retain the stator Cage S.

The rotor shzit't 9 passes throughthe bear inicii (i which is a split bearing having the removable part end into a bushing 11 hold .in the plate l2. A plug' 13 is used to close the opening in the end of the bush- A l sind to retain lubricant therein.

' The plate 12 exactly lits the inside of the outer shell. 5 and it has plurality ot in- A 'eways therethrough as illustrated ut 1 and lil in Figures 11 and 13. The plate l2 is held in a tixed position by the @iure S, and said has two vseries of inf'lined peripheral ope-ninos 15. and 16.

These openings are oonneeted on the outside ol' the rotor and tapering' Vout at the pe riphery. it the other end there are a plurality o'l' slots 23 Whieh are in exactly the reverse position from the slotsEZQ beginning at a p `int near the center piston ring` 2O and extending deeper toward 'the en Yl oi? the rotor which point they terminate in elongated slots fzs indicated in Figure 5.

Under the bearing' 6 there is a fixed plate 2%, While the shaft 9 carrying the rotor has lined plate 25 secured thereto tok ae't as Wear plates tor the thrust bearing` tege The rotor is held in place on the shaft 9 bj; means of the nut 2?.

The head tor Cleaning the tubes comprises a heavy sheltwith two three-armed spiders 31, Each spideil arin is provided with a radially extending slot as indicated at and through each pair ot these slots there extends a shaft 34, each of said shafts n pinfl they cannot escape and c'an'only, motie radially along the slots in which they are placed. Cotter pins 39arensed;` tO-prevent the pin 34 from dropping out of place.

What We claim is as follows, but vvarious modications may ybemade in the construction shown in the drawings'and above particularly described form, Within the-purview of ourinvention. Y

l. A turbine for `boiler flue cleaners comprising a'stator having tiro series of inclined slots Withpassageways extending from one slot to another of the series,and a rotor harl ing two series of slots, ,said rotor litting` the stator whereby steam will pass from one end of the rotor outjthrough the same into the stator and then back iA to Ithe rotor, to

drive thesame. Y

2: In "a turbine the .combination of a slotted casing with a rotor having two series of slotsformed tlierein',rthe arrangement of slots being such that steam passing to the rotor. will pass into, the `end oi the rotor then through its periphery and then back into the rotor through its periphery at an- .othcr portion thereof and be discharged from the rotor at the end o1"- the saine.

3.; In a turbine the combination ot a casA ing' having a plurality or". inclined slotsV therein, and arotor closely littingfsaid casing, said rotorfhaving a plurality of inclined slots arranged to allor,v the entranceo fluid at the end of the rotor dischareting;I the same through itsperiphery and then permitting it tore-enter the periphery or the rotor and linal,lyesca1: e'at the endfor the rotor.

In testimony whereof We have hereunto setv our hands this 23rd day oit March, A. D.
